Manning uses the EEG headband to track her sleeping brain’s “fingerprint”—the pattern of thousands of electrical signals firing across her 180 brain regions. When the fingerprint shows slow waves in brain activity, which correspond with deep sleep, the headband emits a ...
The description of brain activity offered by PSG has for long been acknowledged as incomplete, and attempts have been made to harvest more information from scalp EEG in a search for features relevant for sleep, overlooked by PSG45,46,47. Our work adheres to this aim, while, through fMRI, ...
Thus, we suggest that brain activity obeys similar scheme, with seemingly stochastic dynamics at small scales (neurons), while large scales (EEG) display more coherent behavior or high-dimensional chaos.Sami El BoustaniAlain Destexhephysics
While we sleep, we still experience environmental stimuli — some are harmless, while others can be dangerous enough to warrant us waking up and taking action. K complexes (a pattern of brain wave activity that typically occurs during NREM stage 2 sleep) are thought to protect sleep by prevent...
(SW) index, applied to EEG data (i.e., frequency bands) was examined. Significant differences in SW values were found between the pre-sleep and post-sleep onset phases in both young and older groups, with a reduction in the SW index in the theta band common to both groups. Additionally...
EEG recordings revealed that their brains continued sorting the words into their proper categories. When participants heard "horse," their brain activity looked as if they were preparing the right hand, not the left, to hit a button. The results may help explain how meaningful sounds, such as...
Further research will focus on how to take advantage of our sleeping time. Writing in the journal Current Biology, the research team set out to study the brain ’ s behaviour while awake and during sleep. Using an electroencephalogram ( EEG) , they recorded the brain activity of participants ...
We noticed that averaging a few markers could be sufficient in certain patients to detect amygdalar activity at the surface (P4; P5), while for other patients a larger number of spikes marked on amygdala (P7; P13; P14) was not sufficient to reach detectability (Supplementary Data 1). Still...

Introduction to the Research Areas Music, an auditory art and intellectual brain activity, conveys emotions and facilitates thought communication, representing advanced cognitive activity [1,2].

tasks can lead to differential activity related to arousal instead of the condition under investigation. As one subject remarked “Why are your experiments so boring it is like torture. All you are recording in your experiment is brain activity involved with being bored to death versus sleeping....
